You are naming off compact utility tractors that can have a mower deck option, but many have frontend loaders and even backhoes attached to them.
No one that I know these days of offers "garden tractor packages" with dedicated garden attachments included.
All Cat 0 attachments have been individually priced and priced high. A single bottom plow, a disc, tiller and a cultivator combined practically cost as much as the tractor would. Forget about a 2-row planter, a side row dresser or a spike wheel aerator.
